Ovidiu Panait a402035028 sandbox: u-boot.lds: Remove bogus __bss_start symbol
The sections described in the sandbox linker script are inserted before
data section via "INSERT BEFORE .data;". Running readelf -S on sandbox
u-boot binary shows that the bss section is located after the data
section:

  Section Headers:
  [Nr] Name              Type             Address           Offset

  ...

       000000000000f708  0000000000000000  WA       0     0     32
  [28] .bss              NOBITS           000000000043a720  0023a708
       0000000000018930  0000000000000000  WA       0     0     32

This means that the __bss_start assignment in the linker script is bogus,
as the actual bss section start is located elsewhere. Remove this
assignment, as the __bss_start symbol is not used on sandbox anyway.
